FILM ADHESIVE AND PRODUCTION THEREOF

摘要

A film adhesive mainly comprising a polyimide resin which has a glass transition point of 350 DEG C or below and is soluble in organic solvents, which resin is produced by the ring closure reaction of a reaction product between at least one of the following acid components (A) and (B): (A) 4,4'-oxydiphthalic dianhydride and (B) 3,3',4,4'-biphenyltetracarboxylic dianhydride and/or 3,3',4,4'-benzophenonetetracarboxylic dianhydride, and at least one of the following amine components (C) and (D); (C) a siloxane compound represented by general formula (1) and/or 2,2-bis-(4-(4-aminophenoxy)phenyl)propane, wherein R1 and R2 represent each a divalent C1-C4 aliphatic or aromatic group, R3, R4, R5 and R6 represent each a monovalent aliphatic or aromatic group, and k represents an integer of 1 to 20, and (D) bis(aminophenoxy)benzene and/or dimethylphenylenediamine. <CHEM>
